The GUP Tech pPTSD Douche Edition, short for "prof Pinotte Tone Shaping Device," is a professional-grade 3-band parametric EQ pedal with an integrated clean boost, made by GUP Tech in Saguenay, Quebec, Canada. GUP Tech describes it as delivering surgical precision for guitar tone shaping in your amplifier's effects loop, with a full analog signal path the maker says maintains guitar tone integrity1. It belongs among equalization pedals and, with its level control, can also serve as a boost pedal.
The Douche Edition was listed as sold out on GUP Tech's product page as of 26 October 2026, and the listed sale price is given in British pounds1.
Controls and frequency bands
The pPTSD covers three fully parametric bands, each with a ±12dB boost/cut range, plus an adjustable Q (bandwidth) control for precise frequency targeting1.
| Control | Range | Function |
|---|---|---|
| Low band | 33 to 330 Hz | ±12dB boost/cut1 |
| Mid band | 250 Hz to 2.2 kHz | ±12dB boost/cut1 |
| High band | 1.1 to 11 kHz | ±12dB boost/cut1 |
| Q | Adjustable bandwidth | Precise frequency targeting1 |
| Level | Unity at noon | Volume boost for solos, with a lot of boost available1 |
The Level knob doubles the pedal as a straight volume boost: GUP Tech says unity gain sits at noon, with a lot of volume boost available above that for solos1.
Power and size
The pPTSD runs on 9V DC center negative and draws 48mA1. Its enclosure measures 3.7" x 4.7" x 1.34" (94mm x 119mm x 34mm), a larger footprint than a standard compact pedal, which reflects its three-band parametric layout1. The Douche Edition carries a Neon Yellow finish1.
Where it sits in GUP Tech's range
GUP Tech builds all of its pedals by hand in Saguenay, Quebec, and the Douche Edition line marks limited, brightly finished versions of its circuits. Other GUP Tech EQ and boost designs include the GrindR and its GrindR Douche Edition, the Le Chiou EQ-Boost Douche Edition, and the Donut Douche Edition boost-overdrive1.
Questions
Is the GUP Tech pPTSD an analog EQ?
Yes. GUP Tech describes the pPTSD as having a full analog signal path, which the maker says maintains guitar tone integrity. It is a 3-band parametric equalizer with an integrated clean boost, built as a pedal rather than a digital modeler or rack unit.
Is the pPTSD true bypass?
Yes. GUP Tech states the pPTSD uses true bypass switching, which preserves your guitar's signal when the pedal is disengaged. With the pedal off, your signal passes through without the EQ or boost circuitry in the way.
Can the pPTSD go in an amp's effects loop?
Yes. GUP Tech describes the pPTSD as delivering surgical precision for guitar tone shaping in your amplifier's effects loop. Because it is a full analog signal path pedal, it is suited to that position rather than only in front of the amp.
How much current does the pPTSD draw?
GUP Tech lists the pPTSD's power requirements as 9V DC center negative with a consumption of 48mA. That is more than some simple boost pedals draw, so it is worth keeping in mind when sharing a power supply with other pedals.
What does the Q control do on a parametric EQ?
On the pPTSD, the Q control sets the bandwidth of the frequency band you are adjusting, which GUP Tech describes as allowing precise frequency targeting. A narrow Q affects a small slice of frequencies, useful for cutting a problem resonance, while a wider Q shapes a broader region of your tone.
